To all xi/flout l t nzay concern:

Beit known that I, THOMAS F. KENT, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Incandescent Gas-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to numerals of reference marked thereon. which form a part of this specification.

The objects of this invention are to secure in an incand escent gas-burner improved means for feeding and controlling the gas-supply; to enable the same to be throttled or reduced without impairing or dissipating its pressure; to limit or regulate the adjustability of said gas-supply-controiling'means; to secure an improved construction of mixing-chamber,

especially at its upper or discharge portion; to thereby secure a perfect impingement of the gas against the mantle, resulting in a complete incandescence of the same, and to obtain other advantages and results, some of which may be hereinafter referred to in connection with the description of the working parts.

The invention consists in the improved incandescent gas-lmrner and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like numerals of reference indicate COIIGSIJOHCiIlIg' parts in each of the several figures, Figure 1 is a side View of an incandescent burner complete and having my improvements embodied therein. Fig. 2 is a crosssection of the same upon line (r, Fig. 1; and Figs. 3 and 4 are other cross-sectional views upon lines ;1 and .2, respectively, of Fig. 1, the direction of vision in all said sections being downward. l ig. a vertical central section of my improved burner, and Fig. 6 is a detail plan of the top of the gas-supply-controlling means.

In said drawings, 2 indicates a nozzle adapted to be connected to ordinary house gas lixtures or pipes by screwing. Said nozzle supports my entire burner. being at its outer sides above the wrench rece1v1ng flange 3 threaded, as at 4, to receive a correspond1nglythreaded controlling-sleeve 5, having a milled flange 6 at its lower end to facilitate turning. The upper end of the nozzle 2 is reduced, as at 7, and split, as at 8, terminating in a tapered extremity 9. The sleeve 5 has at its end an aperture 10, whose walls liare inwardly and which is adapted to lit nicely upon the said tapered extremity 9 close to its end. It will be understood, therefore, that to reduce the gas-supply the sleeve 5 is screwed downward upon the nozzle 2 to force the two halves of the split tip 9 more closely together and contract the opening 11 at the end, through which alone gas can escape to the mixing chamber. It should be noted that as this occurs the gas-supply opening is not only contracted, but is brought to occupy within its outside limits at smaller area. There is thus no diffusion of the gas, such as, when the supply is cut down, commonly dissipates the pres sure. By my improved construction the pressure remains the same whether the gas supply is large or small in quantity-that is to say, the pressure of the jet passing into the mixing-chamber.

Preferably a set-screw 12 is mounted in the milled flange 6 of the controlling-sleeve to engage at its inner end, if desired, a stop 13 upon the nozzle 2, and thus limit regulation. In many places the daynessure and nightpressure in the gas-mains vary considerably, and there the said stop 13 of my improved device may be of such length circumferentially of the nozzle that its opposite sides determine the position of the controlling-sleeve for the said different pressures.

The upper portion of the controllirig-sleeve 5 is preferably reduced, as at 14, and threaded to receive an annulaf basepiece 15, supporting the mixing-chamber 16. Said mixing-chamber has apertm'es 17 at its base for the admission of air and above its middle part 18 flares into a cylimlrical upper portion 19, open at its top and adapted to slidably receive a cap 20. Said cap is provided with a. conical top having therein outer and inner circular series of gas-disclntrge openings 21 and 22, respectively. The outer of these gasopenings are close to the cylimlrical walls 23 of the cap and parallel thereto, while those of the inner series are inclined or directed outwardly with respect to the length of the mixing-chamber, as shown in Fig. It will be understood that the mantle an sets at its lower end over the cap 20, being supported at its top by a rod or standard 25, seated in a central socket 26 of the cap. Thus the gas escaping from the outer series of openings 21 is directed upward parallel. to the walls of the mantle and in close proximity thereto, while that escaping from the inner row of apertures is directed outward and also against the mantle to heat the same.

The socket 526, in which the mantle-rod 25 is seated, extends through the top of the cap 20 and is threaded at its lower end, as at 27, to receive a screw 28, which supports a dished gauze flame-guard 29. By removing the said screw, furthermore, the stump of the mantlerod may be forced out in case the same becomes broken off.

A globe-holder of a usual construction known as the closed bottom is mounted upon the mixing-chamber and carries aglobe 31, having air-holes 32 of a type well known in the art. Obviously, however, my improved burner could be employed with other glassware and supports.

Preferably the split or opening8 in the tapered end of the nozzle 2 is enlarged at the center of the extremity of the nozzle, as at 33, so as to give volume to the jet of gas and prevent its being entirely shut off or throttled by the controlling-sleeve.

Having thus described the invention, what I claim as new is 1. In a gas-burner, a mixing-chamber having its upper end adapted tooenter the lower end of a mantle and provided at the top with an outer series of discharge-passages arranged in the direction of the length of the mantlereceiving portion of the mixing-chamber and an inner series of discharge-passages which are directed obliquely outward.

2. In a gas-burner, the combination with a mantle, of a mixing-chamber having a conical upper end and in said end an outer series of discharge-openings directed substantially parallel to the walls of said mantle, and an inner series of openings located at a higher point than said outer series and directed outwardly at the walls of the mantle.

3. In a gas-burner, the combination of a mixingchamber providing an open cylindrical top, a cap fitting said top, and having gas-discharge openings in itself, a central socket extending through said cap and being threaded at its lower portion, a screw entering said threaded portion of the socket from below, a gauze flame-guard supported on said screw, and a mantle-rod in the upper part of said socket.

In testimony that I claim the foregoing I have hereunto set my hand this 12th day of August, 1904.

THOMAS F. KENT.
